MACHINE FOR REMOVING SCALE AND POLISHING WIRE.

SPECIFICATION forming part of Letters Patent No. 762,180, dated June 7 1904. Application filedl'ebruary 27,1904. Serial No. 195,899. (No model.)

To all whmnit WMLZ/ concern:

Be it known that I, FRED MICHOU, acitizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Removing Scale and Polishing Wire, of which the following is a specification.

This invention relates to a machine for mechanically removing scale from and polishing the surface of a continuous length of round or angular wire or rod.

The object of this invention is to produce a .simple and durable machine whichwill effectually remove scale from and polish wire or.

rod in a very rapid and satisfactory manner without requiring much attention.

The embodiment of the invention that is illustrated has a framewhich is adapted to be rapidly reciprocated and rotated and which carries a number of pieces of polishing material that are adapted to be rotated independently of the frame, so that the polishing material reciprocates along, revolves about, and rotates on the surface of the wire or rod that is fed axially through the frame.

Figure. 1 of the accompanying drawings shows a side elevation of this machine. Fig. 2 shows a horizontal section onthe plane indicated by the line 2 2 of Fig. 1, and Fig. 3 shows a vertical section on the plane indicated by the line 3 3.

The base 1 is preferably cast to shape of iron. Movably held in ways on the upper side of the base is a bed 2. A red 3 connects the bed with a crank 4 on the end of a shaft 5, which is supported by suitable bearings in standards attached to the base and is provided with a driving-pulley 6. When the pulley is rotated, the crank by means of the connecting-rod reciprocates the bed. Fastened to the top of the bed are two standards 7 having bearings which support the tubular trunnions 8 of a frame 9. The trunnions are free to rotate but not reciprocate in these bearings. When the bed is reciprocated, the standards holding the trunnions cause the frame to be reciprocated. One of the trunnions extends through a bearing in a standard 10, that is fastened to the top of the base above the bed. 5 This trunnion slides freely'through this fixed bearing. On the outer end of one trunnion is a pulley 11, by nieans of which the frame may be rotated.

The wire or rod to be cleaned of scale and to be polished is fed by any suitable mechans ism through the trunnions of the frame. Supported by the frame, with their inner ends thrusting against the wire or rod, are a number of pieces 12 of grinding and polishing material, such as emery or the like. These pieces have a free movement longitudinally through the supporting-bushings 13, but are held so that they will rotate with the bushings, preferably by flattening one side of each piece and the opening through each bushing. The outer ends of the polishing-pieces are fastened to bars 14, movable on posts 15,that extend outwardl y from the frame. Springs 16, attached to cross-heads 17, thrust against the bars, so as to hold the polishing-pieces against the sur face of the wire or rod with a yielding pressure and feed the pieces as they wear away. The inner bushings 13, that support the polishingpieces, are provided with intermeshing gears 18, and the middle bushing of each set is also provided with a ratchet-Wheel 19. Springpawls 20 are attached to arms 21, fastened to the fixed standard, so as to engage the ratchetwheels, and each time the frame is reciprocated the pawls turn the ratchets and through the gears impart slight rotary movements to the polishing-pieces. It is not necessary, but it is desirable, that the polishing-pieces be rotated in this manner, so that the wire or rod will not wear grooves in the ends of the pieces. If round wire is to be cleaned, the frame is simultaneously reciprocated and ro- ,tated, so as to cause the entire surface of the wire to be subjected to the action of the polishing-pieces both with a longitudinal movement and with a rotary movement. If flat.

be made of different materials or of the same materials having different degrees of coarseness and hardness, and these may be arranged so that the hardest and coarsest will act first and roughly remove the scale and the softest and finest will act last and clean and polish the wire or rod after the coarse scale has been removed.

The pulleys are belted, so that the frame reciprocates and rotates and causes the polishing material to reciprocate longitudinally of the wire very rapidly and to revolve about the wire at high speed. The springs hold the polishing-pieces closely to the wire and feed them forwardly as they become worn down, and as the polishing-pieces are rotated their ends do not become grooved and crumble, so the entire substance is utilized for removing the scale and cleaning and polishing the Wire.

This machine is very efficient, and after it is set in operation long lengths of wire or rod can be cleaned and highly polished in a very satisfactory manner with a little attention.

The invention claimed is- 1. A wire-polishing machine having a base, standards, a frame rotatably supported by the standards, means for rotating the frame, polishing-pieces held by the frame, and means for forcing the polishing-pieces toward the axis of the frame, substantially as specified.

2. A wire-polishing machine having a base, standards, aframe rotatably supported by the standards, means for rotating the frame, polishing-pieces held by the frame, means for forcing the polishing-pieces toward the axis of the frame, and means for rotating the polishing-pieces, substantially as specified.

3. A wire-polishing machine having a base, standards, a frame rotatabl y supported by the standards, means for rotating the frame, means for reciprocating the frame, polishing-pieces held by the frame, and means for forcing the polishing-pieces toward the axis of the frame, substantially as specified.

4. A Wire-polishing machine having a base, standards, aframc rotatably supported by the standards, means for rotating the frame,means for reciprocating the frame, polishing-pieces held by the frame, means for forcing the polishing-pieces toward the axis of the frame, and means for rotating the polishing-pieces, substantially as specified.
